Gravel Tons to Cubic Yards Converter
Convert weight in tons to physical volume in cubic yards based on specific stone aggregate density.
📐 Mathematical Conversion Formula:
Cubic Yards = (Tons × 2,000 lbs) ÷ (Material Density in lbs/cu yd) Reference Conversion Table & Examples
Calculations are based on standard quarry aggregate testing weights at ambient moisture levels.
| Weight in US Tons | Aggregate Preset | Volume (Cubic Yards) | Quick Rule of Thumb |
|---|---|---|---|
| 1 Ton | Pea Gravel (2,800 lbs/yd³) | 0.71 cu yds | 1 ton = 0.71 cubic yards |
| 5 Tons | Crushed Stone #57 (2,700 lbs/yd³) | 3.7 cu yds | 5 tons = 3.70 cubic yards |
| 10 Tons | Crusher Run (3,000 lbs/yd³) | 6.67 cu yds | 10 tons = 6.67 cubic yards |
| 15 Tons | River Rock (2,600 lbs/yd³) | 11.54 cu yds | 15 tons = 11.54 cubic yards |
Standard Density Factors by Aggregate Type
Use these verified density constants to perform custom volume-to-weight conversions:
| Aggregate Material | Density (lbs/cu yd) | Tons per Cu Yd | Tons to Yds Multiplier |
|---|---|---|---|
| Pea Gravel (3/8") | 2800 lbs/yd³ | 1.4 t/yd³ | 0.71 yds/ton |
| Crushed Stone #57 (1/2" - 1") | 2700 lbs/yd³ | 1.35 t/yd³ | 0.74 yds/ton |
| Crusher Run / Dense Grade (DGA) | 3000 lbs/yd³ | 1.5 t/yd³ | 0.67 yds/ton |
| River Rock (1" - 3") | 2600 lbs/yd³ | 1.3 t/yd³ | 0.77 yds/ton |
| Decomposed Granite (DG) | 3000 lbs/yd³ | 1.5 t/yd³ | 0.67 yds/ton |
| Drain Rock / Drainage Gravel (1" - 1.5") | 2600 lbs/yd³ | 1.3 t/yd³ | 0.77 yds/ton |
| Lava Rock (Red / Black) | 1200 lbs/yd³ | 0.6 t/yd³ | 1.67 yds/ton |
Frequently Asked Questions About Gravel Tons to Cubic Yards Converter
How many cubic yards are in 1 ton of gravel?
On average, 1 ton of gravel is between 0.71 and 0.77 cubic yards (approx. 20 cubic feet), depending on whether it is dense crushed rock or lighter round river stone.
Why does gravel weight per cubic yard vary?
Weight depends on moisture content, stone mineral composition (limestone vs granite vs volcanic basalt), and particle size distribution (clean stone vs stone with dust).
